According to Dale S. Beach, Human resource planning is a process of determining and assuring that the organisation will have an adequate number of qualified persons, available at the proper times, performing jobs which meet the needs of the enterprise and which provide satisfaction for the individuals involved.
How much sleep do teens need? Based on current data, we think that most teens need on the order of 9-plus hours nightly to have optimal sleep. The NSF poll data indicate that most teens fall short of this goal, many by a considerable amount. Although we think that the need for sleep does not really change across adolescence, the amount of sleep young people get does decrease in older teens.
If teens need 8 to 10 hours of sleep to do their best and naturally go to sleep around 11:00 pm, one way to get more sleep is to start school later. Teens' natural sleep cycle puts them in conflict with school start times. Most high school students need an alarm clock or a parent to wake them on school days.
